HTML writing number of php while iterations on page

Question

I have a tiny while loop on my page, but it's also writing every iteration of the loop on my page, and I want those iterations (marked on the screenshot) to be not shown, here is the code:

while ($i < ($blocksize / 2) - 1) {?>
    <span class="nowrap"><?= $a.','.$b;?></span>
    <?= $a++; $b--; $i++;?>
    <span class="nowrap"><?= $b.','.$a;?></span>
    <?= $a++; $b--; $i++;?>
<?php };?>

And the output screenshot: Output

Please help me to solve this problem, Thanks everyone!

"Please help me to solve this problem" - What problem? You've just shown us some code and what output it gives you. You need to explain what result you're expecting or we won't have a clue. You also need to let us know what all those unknown variables contains. — M. Eriksson

Remove the echoes<?= $a++; $b--; $i++;?> to <?php $a++; $b--; $i++;?>. <?= is the same as <?php echo . — M. Eriksson

The problem is that you're using <?= for the values you don't want to output. <?= is short hand for <?php echo.

If you just want to execute a statement but not output anything, just use <?php.

So change

<?= $a++; $b--; $i++;?>

to

<?php $a++; $b--; $i++;?>

Try this

while ($i < ($blocksize / 2) - 1) {?>
    <span class="nowrap"><?= $a.','.$b;?></span>
    <?php $a++; $b--; $i++;?> // remove = here
    <span class="nowrap"><?= $b.','.$a;?></span>
    <?php $a++; $b--; $i++;?> //remove = here
<?php };?>

I would recommend to always use <?php instead of short tags <?, since they have been disabled by default since a bunch of years back.
